CARLSEN /M 1 M17 ATTORNEY United States Patent 01 hce 3,138,096 Patented June 23., 1964 3,138,096 ENLARGED HAND PRINTING STAMPS Carl E. Carlsen, 867 3rd Ave., New York, N.Y. Filed Sept. 17, 1963, Ser. No. 309,568 2 Claims. (Cl. 101125) This invention is a continuation, in part, of my application for patent, Ser. No. 269,025, filed March 29, 1963.

The present application has for its object to provide an enlargement of my device, as referred to in the above application, and embodies new features especially adapted for a larger portable printing device, whereby the printing pads of the latter may be quickly renewed, due to a special construction of the means of attachment of said pads.

Further improvements, especially usfeul in connection with a portable printing device, resides in the construction of the stencil, permitting both ends of the latter, when desired, to remain attached to a backing sheet, when the stencil is being prepared. This feature is of special importance, when the stencil is being prepared with a stylus or ball point pen, as in this instance the backing sheet acts as a frame.

However, when the backing sheet is removed, the stencil remains re-enforced in close proximity to the actual printing space, because of a second re-enforcement by a thinner paper at each end of the stencil, whereby to prevent the latter from being damaged, when the stamp is placed on or removed from the paper.

In the drawing, in which corresponding characters of eference indicate similar parts in all views,

FIGURE 1 is an exploded view, showing two parts comprising my enlarged printing device.

FIGURE 2 is a top plan view of a stencil.

FIGURE 3 is a perspective view, showing said enlarged printing device assembled.

FIGURE 4 is an end view of my said device.

Referring more particularly to the drawing, the numeral indicates the upper part of my printing device; a bridge 11 is secured to the latter, which is provided with a handle 12.

A storage pad 13 is attached underneath the said upper part 10 by means of clips 14 fastened to the said storage pad, as shown in the cut-away portion in FIGURE 1, said clips projecting through the openings 15.

Projections 16 are secured to one side of said upper part 10 of the printing device and made to engage openings 17 in the lower part of the printing device.

The opposite side of the lower part of the printing device is at the top formed with a projection 18, which, when assembling the upper and lower parts, secures these parts together, permitting at the same time the storage pad 13 to be squeezed therebetween.

A printing cylinder 19 is formed with perforations 20 and has cut-away portions 21, 21 at each side.

The said printing cylinder 19 is bent upon itself, as shown at 22, and has upon its outer side prongs 23 adapted to engage a stencil 24 by means of slots 25 in the latter.

The opposite side of the printing cylinder 19 terminates in a rectangular bend 26; a separate rectangularly bent part 27 is springily attached to said rectangular bend 26 of the printing cylinder by means of pins 28 encircled by springs 29; the said part 27 is upon its outer side formed with prongs 30 adapted to engage openings 31 in the stencil, thereby applying a pull to said stencil.

The printing cylinder is upon its outer side at the four upper corners made with projecting members 32 adapted to receive tiny bars 33 upon which the printing pad 34, which is formed with loops at each end, is mounted.

A special feature consists in having a re-enforcement 36 in addition to the regular backing sheet 35.

Thus, when the regular backing sheet has been removed, the stencil nevertheless remains re-enforced with a thin suitable paper close to the actual printing space 37 of the stencil, and thus straightens the stencil at the place where the stamp is placed upon and removed from the paper to be printed.

What I claim as my invention, and desire to secure by Letters Patent of the United Sates, is:

1. An enlarged hand printing stamp comprising an upper part of a printing device, a bridge secured to the latter, a storage pad attached underneath said upper part, and :clips fastened to the storage pad and projecting through openings in securing said storage pad to the upper part, projections fastened to one side of the upper part and engaging openings in a lower part of the printing device; second projections formed at the top of the opposite side of the lower part of the printing device securing said upper and lower parts together and squeezing the storage pad between said parts, a printing cylinder formed with perforations and cut-away portions at each side, said printing cylinder being bent upon itself, prongs upon the outer side of the latter and adapted to engage a stencil, the opposite side of the printing cylinder terminating in a rectangular bend, a separate rectangularly bent part springily attached to the former, pins encircled by springs and securing said rectangular parts together whereby to apply a pull to the stencil, prongs upon the outer side of the separate rectangularly bent part adapted to engage openings in the stencil, projections upon the outer side at the four upper corners of the printing cylinder, tiny bars received by said projections, the printing pad having loops at each end adapted to engage said tiny bars, which attach the printing pad.

2. In a device, as claimed in claim 1, a backing sheet, a r e-enforcement in addition to the latter, whereby when the regular backing sheet is removed, the stencil remains re-enforced by a thin paper close to the printing space.
